Blood tests via cellphone

This may officially be taking this whole
cellphones-as-health-diagnostic-tools thing a little too
far: researchers in Sweden have developed a way to perform basic blood tests with a cellphone. The whole set up
consists of a little disposable microfluidic sensor that connects to a cellphone. The sensor, which is powered by your
cellphone's battery, displays results as different light signals on a chip; you're then supposed to photograph the chip
with the camera on your phone (see how it all ties together?) and then send the pic off to a doctor or lab for
analysis. Anyway, besides freaking out anyone who doesn't like blood, the sensor should eventually be able to check for
any "biomarker for which there is an existing antibody."
